FASTENING DEVICE FOR BOTTLES, 80C.

SPECIFICATION forming part of Letters Patent No. 427,590, dated May 13, 1890).

Application filed February 21, 1890- Serial No. 341,355. (No model.)

To all whom it may concern:

Be it known that I, DAVID N. MARTIN, of Lawrence, in thecounty of Essex and State of Massachusetts, have invented new and useful linprovemei'its in Fastening Devices for Bottles, Cans, &c., of which the following is a specification.

This is a device for rigidly securing in a 1iquid-tight manner the stopples or covers to bottles, cans, and similar vessels, and so socuring them that they maybe readily opened and closed.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is an elevation of a glue-pot with my device applied thereto. Fig. 2 is a vertical is a vertical section on line y, Fig. 4. Fig. 4 is a plan. Fig. 5 is a perspective View of the fastening wire removed.

A represents the body of the glue-pot, with is neck A provided with the annular flange B is the cover, of substantially the shape shown, and with its sides B adapted to fit over the neck A of the glue-pot.

D is a platform, made, preferably, of tin,

, whose supporting sides are bent, as shown,

at right angles and solderedor otherwise rigidly secured to the cover.

D D" are wings extending from opposite sides of the platform, said wings being bent down at substantially right angles at D whereby horizontal parallel passages are provided, as shown in Fig. 3.

Both the cover B and platform D are perforated to receive the brush-handle O, and a layer of rubber c is preferably inserted between the cover and platform.

The wire fastener consists of the central substantially straight or slightly-curved portion E, parallel side portions E, bent so that their central parts are decidedly higher than their ends, forming arches, the portions E bent back nearly parallel with the portions E, and the loop portions E, whose ends catch under the annular flanges r The arches or arched portions E are not formed in the shape of curves or arcs of circles, but consist each of two straight lines forming an obtuse angle for each arch so far as the nature of the wire will allow a true angle to be formed, such angles or apexes being substantially opposite or on a line with the ends or bearing portions of the loops E. The obj ect of making these arches angular instead of curved is to prevent the under sides of the wire at those portions from crowding too hard or for too great a portion of their length upon the cover when the wire fastener is being pushed into locking position; hence necessitating too great force to perform the operation. This wire is placed, as shown in the drawings, with its arched portions E on the baseB and within the passages formed by the wings D of the platform, said passages being of sufficient height to accommodate the arched wire.

When the wire fastener is in position, as shown, the front ends of arched portions E and the portion E press with considerable power on the base B of the cover and hold it tightly in position. It will be seen, therefore, that the wire fastener bears on the cover when fastened at three pointsviz., the front' ends of the angle-shaped arches E and the portion E. The tops of the arches are not intended to touch the platform, and said platform performs no part in holding the cover in position, but serves principally as a means for guiding the fastening-wire in its movement and for preventing it from becoming detached and lost.

The wire fastener is released by pressing with the thumbs on the portions E, and crowded back into position by reverse pressure on the same parts.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the vessel pro vided with the flange A. and cover 13, of the wire fastener described, consisting of the central portion E, the arched portions E bent, as shown, into the shape of obtuse angles, connecting portions E, and loops or catches E', the highest portions or obtuse angles forming the apexes of said portions E being substantially opposite or on a line with the bearing portions of said loops or catches, whereby said wire fastener when in looking position bears on said cover at three pointsviz., the portion E and the front ends of the arched portions E, substantially as set forth.

2. In combination, the vessel provided with the flange A, the wire comprising the arched portions E, the cover B, connecting portions E, and loops or catches E, and the raised platform D, provided with the wings D, whereby covered passages are provided for the arched portions of the wire fastening, said platform being supported by the cover, 10 substantially as described.

DAVID N. MARTIN.
